UMI's Stage 1.5 kit is the simple way to dramatically improve the handling and performance of your 1968-1972 Chevelle. We start with our original Stage 1 kit and take it to the next level by adding UMI's new race worthy rebound adjustable monotube shocks. The 20-click adjustment range covers street cruising, corner carving and even autocross or road course use. The Stage 1.5 kit also tunes up the camber curve by including 1/2 inch taller than stock upper ball joints that easily bolt to factory and most aftermarket a-arms. High performance lowering springs feature medium stiffness to control body movement and reduce floating while still providing a comfortable, sporty ride. The UMI rebound adjustable monotube shocks feature a large diameter piston and nitrogen charge to dampen bumps and provide a crisp feel without being harsh. The shock is built with heavy duty mounts to ensure durability and fits in the stock location. They are easily adjustable with an external adjustment knob - no tools required. Stage 1.5 balances out with our tried and true 1.25 inch front sway bar and 1 inch rear sway bars reducing body roll and providing excellent chassis balance when handling at the limit. Every component in this kit, as with all UMI products, is made in the USA.
